Dell Support Centre.

Have had a Dell 1545 laptop for over 2 years now.Vista and 32 bit. In the past I have had prompts from Dell and have used their support centre for scanning, and downloading drivers, etc. Recently the message comes onto the screen- Dell Support Centre has stopped working, Windows is looking for a solution.
Is the Dell Support Centre necessary for me? One friend has told me to uninstall Dell Support Centre as it is not absolutely necessary. Correct or not. ??
Any guidance and answers will be appreciated.
